SUMMARY
CG30S Low temp fluid loss additive is a synthetic polymer fluid loss additive, which could effectively reduce water loss during oil gas cementing process.
Applicable for medium and high temperature wells (below 150℃ (302℉, BHCT)).
It can be used in lightweight, normal density or high density cement slurry systems.
Mixing water: from fresh water to salt-saturated water.
Compatible well with other additives.
Recommended dosage: 0.6-2.5% (BWOC).
